Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a plug-in appliance mounting device for a bus duct.

In the conventional plug-in device, as shown in FIG. The bolt 1 is engaged with the bent portions 18 formed at both ends.
5, or by sandwiching the bent portions 18 formed at both ends of the top plate of the bus duct with a mouth-shaped fixing fitting 19 fixed to the bottom plate of the plug-in device 14 and a washer 20, as shown in FIG. Generally, plug-in appliances have a cover box body made of iron and a circuit breaker, a circuit breaker, etc.
Because switches and other components are attached, the device is quite heavy and has a large external shape, and it takes a lot of effort to align the fixture fixing brackets when installing the fixture, especially when the bus duct is installed next to a wall. In such places, tightening the bolts of the mounting bracket by inserting one's hand into a narrow gap near the wall is extremely difficult and takes a long time.

The present invention has been made for the purpose of eliminating the above-mentioned drawbacks, and an embodiment of the present invention will be described below with reference to the drawings. In FIG.
is an L-shaped metal fitting fixed to the wall side of the box of plug-in device 3, 4
A tightening bolt I- is inserted into a hole 5 with a large diameter drilled in the new bent part of the L-shaped fitting 2 so as to be tiltable, and a stopper is provided at the base of the bolt that comes into contact with the lower surface of the bent part of the L-shaped fitting 2. 6 is installation using screws or other methods.

Reference numeral 7 denotes a fixing fitting for attaching the plug-in device 3 to the bus duct, and the fixing fitting 7 is tiltably inserted into a guide slot 12 formed in the bottom plate 11 of the plug-in device box body, as shown by the dotted line in FIG. A hook-shaped bent part 8 that engages with the upper plate bent part 1 of the bus duct is formed at the tip, and an inclined bent part 9 is formed in the middle. A bolt 4, which is inserted in a tiltable manner, is inserted into the bent part of the rectangular metal fitting 2, and by tightening the ports 1 to 4, the inclined bent part 9 is tilted upward using the elongated hole 12 as a guide. The plug-in device 3 is pulled up while drawing a trajectory, and the hook-shaped bent portion 8 at the tip engages with the new bent portion 1 of the bus duct to fix the plug-in device 3.

As described above, the present invention has an elongated hole drilled in the bottom plate 11 of the box body of the plug-in device 3 for the tightening bolt 4 which is tiltably inserted into the L-shaped fitting 2 fixed to the inner wall of the box body of the plug-in device 3. 12, and has a hook-shaped bent part 8 that engages with the bent part 1 of the top plate of the bus duct to fix the plug-in device 3, and a fixing fitting 7 formed with a new inclined part 9 in the middle. Since the plug-in device 3 is installed by screwing together, it is extremely easy to install the plug-in device 3 to the bus duct by removing the lid 13 of the device 3 and tightening the tightening bolt provided inside the box body with a spanner, etc. It is easy to work on-site, and has the advantage of being easy and quick to install in tight spaces, such as near walls.
